Easily installed in ~15 minutes once under the car, this is a no brainer over installing a wideband gauge assembly. No running wires through the firewall or mounting annoying gauge pods, simply install the sensor, plug in the controller, secure and you are ready to go!


See our installation video on YouTube that covers the complete installation start to finish, or find the PDF install guide in the downloads section.


Note: Your tune will need this logging and display feature activated. Simply let your tuner know you are now logging the wideband through the MAF VOLTAGE INPUT signal and for them to calibrate the input ( 0.5v=8.5 AFR, 4.5v=18.00 AFR). IAT sensor will also need calibrated for the AEM/GM IAT Sensor.
